Customer Reviews

Finally... a solution to disposable alkalines
I've traditionally maintained both disposables for electronics that slowly run down the battery, and rechargeables for everything else.

Eneloops now take care of all my needs. The flashlight still works after sitting in a drawer for months and high discharge items need less charging too... thanks to the low self-discharge rate.

Because these have such a low discharge rate spare batteries don't need to be permanently tethered to the charger. Just charge them and set them aside until needed... you'll save a bit of energy by unplugging your charger too.

Finally, Rechargeable Batteries That Has Shelf Life Close to Alkalines
The biggest drawback for Nickel Metal Hydride batteries is the shelf life. I got gadgets and toys all around the house, so I constantly charging batteries to have them ready when I need them. There will be very little juice left if you put them in the shelf unused for a couple of months. A waste of time and energy. Hence, one of the biggest advancement in battery technology is the arrival of the new low discharge Nickel Metal Hydride batteries. This is another great step in helping the environment. I have very few left of the old batteries since I started to replace all of them with low discharge batteries. Eneloops and Duracell are 2 of the best of its kind.

Pros:
-Low discharge.
-Fine quality product. Well constructed
-Conventional size and dimension.
-You can use your existing NiMh charger for these batteries

Cons:
-More expensive than ordinary NiMh
-Not available at many brick & mortar stores

My favorite rechargeable battery brand
These batteries are great. They last long, can be recharged in a fairly decent amount of time, and best of all, they maintain their charge for over a year! No more having to recharge your batteries if you don't use the device for a month. These are much more cost-effective than alkaline batteries. I have the AA and AAA versions of these batteries and use them for all my appliances.
